To all when: it new concern:

Be it known thnt i, it I. TICANllF-TR ll. l lDVr'MllJE-Q ll. citimen ofthe United States, n ling in; Long-hutch, in the county of Lon rlngelesznnl finite oi tnlil'ornin, have in.- vented new and usel'nllilllliUVOlllClllzl in .ltotory l 1-- gines, of which the following is ns ilii'rntion.

An Ubjoot ol my invention is to p1,Vi(lD means WlltllU by steam or otherAgency employed in rotary engines is admitted at both ends of the rotarypiston huh, and thereby equalize the pr we fill either ornl thereof.

Another ohjectis: to pn Lflt: on inljnslwtlill: cut oil for the inletports oi the engine.

Another o bjoct is to provide it re large power for the size thereof.

Having described my invention what l claim as new and desireto secure by .liettors Patent is:--

1. In a rotary engine, the combination of a. piston cylinder and onabutment cylinder, said piston cylinder previilod with n piston blttiexhaust grooves and inlet ports, said. abutment cylinder being providedwith a recess; end plntes having: linnnlur inlet grooves in their facesand an exhaust port; and o, steam cut oil ntljustably mounted in theinlet grooves;

1n 1m ermine or. the character described, :i rotary lllslen cylindercarrying ii piston hlnxle and bovine in one]! end thereof on exlnn lport cormnuni V n; on allotment eyilnder havingon the periphery thereof:1 piston blade wing recess, the said cylinders worknbly (minim-ted byspur gears, in combination with a casing snrronndint, said cylinders:nul having it each end thereof adjnceotto the piston cylinder anannular inlet groove, the snltl piston cylinder having on either 92111thereof on inlet port communicating with the inlet groove; :1 shutoff'adjustably secured in the inlet groove, substantially as hereinshown and described 3. In :1 rotary engine 01 the character described, apiston cylinder carrying a piston blade the entire length thereof andhaving in each end thereof an exhaust groove communicating with anexhaust port, the said cylinderhcing provided atcuch end with an exhaustport in ad- VI-ZUCE 01 the piston blades and provided at each end in therear of the piston blades with inlet ports, in combjnw tion with acasing having in each end thereof an annular inlet groove; and 9. checkadjustahly secured in the inlet groove.

In witness that I claim the foregoing I have hereunto subscribed my namethis 16th day of February, 1907.
